Hi Experts,

I am asking for my customer here.

Q1.ADCSOCA0 and ADCSOCB0, The FMEDA pin selection includes ADCSOCA0 and ADCSOCB0. Are these external pins on the chip?

Q2.We can't find the custom diagnostics circled below in the safety manual? Could you point it to us? Thanks.

    Let me check on these and get back to you.

    What you show are the subparts of the SYSTEM and XBAR modules in the MCU. Custom diagnostics tab allows customer to specify their own safety mechanism for covering these subparts. To cover SYSTEM and XBAR customer can use the standard safety mechanisms listed in the "Safety Mechanism Tailoring" tab.

    These are the ADC start of conversion signals generated by the EPWM. These are can be used for debug purposes, but my guess is that customer would not use this function.
